The Department for the Environment has suggested a long-term plan involving alternative energy sources, such as wind and tidal, and reducing waste.

Minister Deputy Rob Duhamel said changes needed to be made now to ensure the wellbeing of future generations.

The department has asked members of the public to comment on the proposals before the end of January.

Dr Louise Magris, the director of environmental policy, said the plan sets out 30 actions for reducing energy consumption.

Previous surveys in Jersey have found one third of emissions comes from cars and other transport, and another third for domestic heating and power within the home, and the remainder for running essential services and powering businesses and manufacturing activities.

Since a green paper was published in 2008, more than 1,300 homes have been insulated through the Energy Efficiency Service.

Dr Magris said the plan proposed developing and extending this service and the role renewable energy could be play in improving Jersey's future energy security.
